Currently, extensive research has been conducted on timber-concrete composite beams both domestically and internationally. Peng et al. This study addressed the issue of scale inconsistency in the evaluation of the flexural performance of timber-concrete composite beams. The aim was to develop an innovative equivalent data transformation method to enable consistent comparative analysis of the performance of timber-concrete composite beams under different loading modes on a single scale. Through experimental research on a 1:3 scaled model under monotonic static loading, this study successfully converted three-point loading test results to four-point loading test results for the first time. The load-deflection data were normalized to ensure the comparability of composite beam performance under different materials and parameters. The experimental results showed that the test beams exhibit good elasticity and stability. The equivalent data transformation method proposed in this study can provide a new tool for design optimization and performance prediction research in this field.

摘要

Currently, extensive research has been conducted on timber-concrete composite beams both domestically and internationally. Peng et al. This study addressed the issue of scale inconsistency in the evaluation of the flexural performance of timber-concrete composite beams. The aim was to develop an innovative equivalent data transformation method to enable consistent comparative analysis of the performance of timber-concrete composite beams under different loading modes on a single scale. Through experimental research on a 1:3 scaled model under monotonic static loading, this study successfully converted three-point loading test results to four-point loading test results for the first time. The load-deflection data were normalized to ensure the comparability of composite beam performance under different materials and parameters. The experimental results showed that the test beams exhibit good elasticity and stability. The equivalent data transformation method proposed in this study can provide a new tool for design optimization and performance prediction research in this field.
